This is a typical list of group photographs that I shoot at weddings. This is normally done shortly after the ceremony and before the wedding breakfast.
Each shot can take 2-3 minutes to set up so you should allow 20 minutes for this. For this reason I recommend this list or a similar number of shots – i.e. 10 group shots as an absolute maximum. In my experience, guests and the wedding party lose interest if they are kept away from the reception for more than 30 minutes. This comes through in the expressions on the photographs which defeats the purpose of marking the celebration in this way!
